= 10 curely holding therailsagainst creepage rel-` ative to the ties 1 i Y Another'object of the invention isthe pro,- vision of atie platefforj concrete tieshaving transverse displacementri but for reliably Y v holding it against vertical displacement-*and eliminating play between the tie plate and the rail.v

A still further object is to, provide a Vtie plate of this character which dispenses with spikes, bolts or equivalent auxiliary fastening devices and in which its parts are so designed and constructed as to eect their ready 25 assemblage within` afminimum peri-od of time and to affordgreater safety of travel.

In the accompanying drawings Figure 1 is a perspective view of a railroad rail and 'tie showing my improved Vtie 1 30 plate in connection therewith. Figure 2 is an enlarged cross section taken -in the plane of line 2 2, Figure 1. Figure 3 is a vertical section taken on `line 3&3, Figure 2. Figure l is a sectional perspectve'view of the tie 35 plate. Figure 51s a perspective of oneof the locking keys. l 4 y Referring now to the drawings, 10 indicates one ofthe ties, which, for the purpose of my invention, are made of concrete or like 40 material, and 11 indicates one ofthe railroad rails.

My improved fastening means for securing the rail to the ties consists of a'tie plate'.` 12 made of malleable iron orother approprir ate materialand of substantially rectangular shape in plan. Depending from the opposite ends of this plateare anchoringv elements or yokes 13 adaptedto be embedded in the concrete tie` for Vsecurely holding the plate 5 thereon. i As shown in Figure 1 of the draw-V relation, and the corresponding contiguous ings, theseanchoring yokes are preferably Y U-shaped to eifectuallyholdfthe plate against longitudinaland transverse displacement as y well as Avertical 'displacement relative to the tie. While ltheVJ anchoring elements alrer55.` shown as beingv practically integrally united Awith the tie plate, whereby thetie` plate is anchored to the tie during its manufacture, it is to be understood that, if desired, the yokes 13V may be independently embedded in the tie and the plate provided with openings adjacent its` four cornersrfor receiving the i Y, yoke-Shanks and boltingY said plate thereto. effective and efficient means for not only an- 15 choring the railagainstylongitudinal and y distance from the-longitudinal edges of the rail base and from thetop sides-thereof, 70

`respectivelyas 'seen inv Figure 2.V `The inner edges of the overhanginglug-flanges 17 preferably lterminate at a poi-nt vto/provide ya ga'p between them vof vsuiiicient width to allow for thefree passage ofthe rail-bar be- 5 tween them'in effecting the application and removal of therail to ,and'from the tie'plate.

Adapted for insertion in the resulting spaces formed between the `lugs land the ,adjoin ing portions of the rail 11 are keys or L- shaped locking bars 18 which serve to re` `liably clamp the rail to the tie plate. The

upright portion 19 of each key rests at'its lower edge on the tie plate .and its opposite side faces engage the lugfface 15 and the adjoining edge of the rail-base, respectively. The horizontal portion20 Vof the key overhangs the. rail-base with its underside en` gaging the marginal top side of the latter' and with its top side engagingthe lug-,face $0 16. In order toeifect aiirm vgripping action of the keys 18, theirupper and lower:A faces 21,22 are slightly inclined in the direction of their length andin vsubstantially parallel faces of `the lug-flanges 17 and tieY plate 12 are similarly inclined, the bearing face of the plate being preferably formed bv a recess or notch23 `having an inclined bottom'disposed substantially parallel 'to andvertically` be# GG neath the face of said lug-flange. The undersurface of the key portion 20, as regards the direction of its length, is parallel with that of the rail-base while crosswise of the latter it conforms to the inclination of the top surface thereof. By this construct-ion, a practically double, wedge-like action is produced between the locking .keys and the contiguous bearing walls of the tie plate and rail, thereby effectually holding the rail onto the plate to prevent its vertical displacement and positively resisting creepage of the rail relative to the plate. If desired, the top and bottom faces of the key-,portions 2O1inay be provided with teats or button-like projections 24 which serve to increase the frictional grip between the parts and allow for any variation or unevenness 1n the surface contours of the parts with which the keys conone key :being driven into place from -one side of the plate and the other from the opposite side thereof, whereby an effective gripping of the rail from oppositedirections is obtained, the lockingraction of one key complementing that ofthe other. Further, by this arrangement, the same locking key `is used for either side ofthe plate, thus eliminating the `necessity of right and left for this purpose.

lVhile my invention is particularly intended for use in connection with railroad rails, it may be used with equal effect in structural steel work.

I claim is my invention 1. A fastening` device for railroad rails and the like, comprising a plate adapted -for attachment to a support, hook-shaped 'lugs rising from opposite sides of said ,plate for receiving the rail between them in spaced relation thereto, the underside of the overhanging portion of each lugbeing inclined in a direction lengthwise of the rail and the top side of the plate beneath said overhanging hook-portion being similarly inclined, and locking bars disposed in `the spaces between the rail and said plate-lugs and each having its top and bottoni faces inclined in substantially parallel relation to the opposing inclined sides of the plate and its hook.

2. A fastening device for railroad rails and the like, comprising a vplate adapted for attachment .to a support, hook-shaped lugs rising from opposite sides of said plate for receiving the rail vbetween them `in spaced relation thereto, that part of .the plate beneath each over-hanging hook-portion hav inga recess therein substantially parallel to 3. A fastening device for railroad rails .and the like, comprising a plate adapted for attachment to a support, hook-shaped lugs rising from opposite sides of said plate for receiving the rail between them in spaced relation thereto, the underside of the overhanging `portion of each lug being inclined in a direction lengthwise of the rail and the top side of the plate `beneath its correspond ing lug having a recess therein substantially parallel to the rail, .the bottom ,of said recess being likewise inclined, and substantially L- shaped locking bars disposed `in the spaces' between the rail and said lugs and each embracing the :contiguous longitudinal edge of Athe .rail at its inner side and being embraced by theicontiguous facesof the plate and lugs .at itsouter side, the upper and lower faces of each bar being` inclined inaecordance with the corresponding faces-ofthe plate-lug and lplate-recess and the lunderside of the ovcrhanging portion of each `bar conforming to the surface of the rail-base.
